MFJ has an antenna (1764) that is a 1/2 wave dipole on 6m and what they call 2 
stacked 5/8 wave antennas for 2m.  However, they also have a stacking kit for 
this (the 1766) where you can stack 2 of these antennas to give you 2 stacked 
dipoles on 6m-maybe more like 2 dipoles fed in phase(?) but also 4 stacked 5/8 
waves on 2m.  Here is what their website says about this:

"Gives you four times the gain of a single 5/8 wave. Includes 2 MFJ-1764 5/8 
Wave antennas, phasing cables. Doubles gain on 6 Meters"

The stacking distance between the 2 dipole feedpoints is 12 feet.  Now, what 
kind of gain could one expect on 2 meters with this mounted horizontally?  I am 
guessing that 6 meter gain should be 3Dbd or so.
